CLOSURE FOR NON-REFILLABLE BOTTLES.

Specification of Letters Patent.

Patented Mar. 2, 1920.

Application filed March 20, 1919. Serial No. 283,696.

To all whom it may concern:

Be it known that I, GENOWEFA OLSZEW- SKA, a citizen of Poland, having declared my intention to become a citizen of the United States of America, residing at Adena, in the county of Jefferson and State of Ohio, have invented certain new and useful Improvements in Closures for Non-Refillable Bottles, of which the following is a specification.

The primary object of the invention is the provision of a valve outlet for a receptacle such as a bottle permitting the contents to freely flow out of the bottle when inverted but preventing the entrance of fluid into the bottle for refilling the same when the bottle is positioned upright.

A furtherpbject of the invention is to provide an automatic closure for a bottle in its normal upright position so that the usual cork or stopper member may be dispensed with, the bottle being automatically opened upon inverting for pouring the contents out of the same.

With these general objects in View, the invention which possesses great simplicity and is easy and inexpensive to manufacture, will be fully described in connection with the accompanying drawing in which like designating characters refer to corresponding parts throughout the several views.

In the drawings,

Figure 1 is a longitudinal sectional view through the neck portion of a bottle provided with my invention with the bottle in its normal upright closed position,

Fig. 2 is a similar view with the bottle in its inverted open position,

Figs. 3 and 4 are enlarged transverse sec tional views taken upon lines IIIIII and IV--IV, respectively, of Fig. 1,

Figs. 5 and 6 are enlarged transverse sectional views taken upon lines VV and VI VI, respectively, of Fig. 2, and

Fig. 7 is an enlarged perspective view of the valve member employed.

My valve may be readily positioned in the outlet spout or neck of any container and is herein illustrated operatively mounted in the neck 10 of a bottle 11.

A casing or funnel 12 in the shape of a truncated cone is mounted in the passage or bore 13 of the neck 10 with its smaller end 14.- extending toward the bottle 11 while a resilient serrated flange 15 projecting from the outer larger end of the casing 12 firmly seats in an annular groove 16 formed in the bore 13, such seating taking place automatically upon forcing the funnel 12 to the required position in the bore 13.

A circular strainer 17 is then forced into the funnel 12 frictionally engaging in an inner groove 18 of the funnel so as to position the strainer adjacent the enlarged outer end of the funnel.

Before the funnel 12 is inserted in the bottle neck 10, a valve or plug 19 is provided in the funnel tapered for fitting the same to automatically close the passage through the funnel when the funnel and bottle are positioned upright, a semicircular weight 20 being rigidly carried by the plug 19, secured thereto by a rod 21 passing axially through the said plug.

The weight 20 is spaced sufficiently from the plug 19 to permit the plug to open and close within the funnel 12, the passage 13 being closed against the entrance of any fluid when the bottle is positioned upright as will be apparent from Fig. 1 of the drawing.

Oblique openings 22 through the weight 20 are adapted to permit fluid to pass from the bottle 11 to the interior of the funnel 12 through the contracted open end 14 thereof when the bottle is inverted as illustrated in Fig. 2. Upon inverting the bottle, the weight 20 falls upon the end 1 1 of the funnel with the openings 22 communicating with the interior thereof and with the plug 19 open so that fluid from the bottle 11 passies outwardly through the neck 10 as de slre My bottle valve construction possesses simplicity whereby the same is easy and cheap to manufacture but at the same time provides means whereby a bottle or other container closes automatically when left in its normal upright position.

What I claim as new is In combination with a bottle neck having an annular groove therein intermediate its ends, a funnel member having a flange at its enlarged end positioned within said neck with the peripheral edge thereof secured in the annular groove to retain the funnel member against displacement, a strainer secured within the enlarged end of said funnel member, a tapering solid valve slidably mounted in said funnel member, a rod secured by one end to said plug and its free end extending out beyond the small end of said funnel member, and a semispherical solid Weight secured on the free end of said rod and having a plurality of fluid passages therein communicating with the funnel member when said bottle is inverted and the Weight seated upon the small end of the funnel member by the longitudinal sliding ac- 10 tion of the Valve plug.

In testimony whereof Iafiix my signature.
